2. Excluded third-party content

The permission above does NOT cover embedded third-party audio, original
SAO Utils / NERvGear material, SAO characters, names, trademarks, or any other
pre-existing third-party rights. In particular, client.js embeds the three
original WAV recordings identified in THIRD_PARTY_NOTICES.md. Their inclusion
does not establish that the project author owns or can license those recordings.
No confirmed redistribution license for these recordings was found in the
supplied material. All such rights remain with their respective owners.

This is not a blanket MIT license for the built client or the complete bundle.
No license to the excluded content is granted here. Anyone redistributing or
reusing it must establish the applicable permissions independently. The new
integration and browser implementation do not claim ownership of the original
work or recovered scene design. Attribution is not a substitute for permission.

See THIRD_PARTY_NOTICES.md and SOURCE.md for provenance and scope.
